LUTHER L. KENNEDY, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGEN THALER LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

LlNOTYPE-MACHINE.

Patented Dec. 12, 1905.

To all whom, it may concern-.-

Be it known that I, LUTHER L. KENNEDY, of Brooklyn, county of Kings, andState of New York, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

The aim of my invention is to adapt the molds of the Mergenthalerlinotype shown in Letters Patent N 0. 557,000 and of kindred machines toproduce at will solidfiat slugs or linotypes of uniform thickness orlinotypes recessed in one side, as shown in Letters Patent of the UnitedStates N 0. 665,326 to Isaiah Hall.

To this end the invention consists in a liner or core of peculiar formadapted to be inserted and secured within the ordinary linotype-moldsand in the combination of such liner with the mold.

While the liner may be modified in detail to adapt it for application tolinotype-molds of the various forms in use, I prefer to employ it inconnection with the so-called universallyadjustable mold represented inLetters Patent of the United States to J. R. Rogers, No. 620,804, and inthe accompanying drawings I have illustrated such application. A Rogersmold provided with an improved liner forms a convertible or changeablemold which may be used to cast either solid slugs or recessed slugs atwill.

Figure 1 is a front view of a linotype-mold having my liner appliedtherein. Fig. 2 is a rear elevation of the same. Figs. 3, 4, and 5 arecross-sections on correspondingly-numbered lines of Figs. 1 and 2. Fig.6 is a perspective view of the liner. Fig. 7 is a per spective view ofone of the slugs or linotypes. Fig. 8 is a perspective view of amodified form of liner.

Referring to the drawings, A represents the body portion of the moldpresenting a fiat upper surface; B, the cap portion overlying the bodyand presenting an under surface parallel with the top surface of thebody.

0 and O are two liners or spacing-pieces seated between the cap and bodyat opposite ends for the double purpose ofseparating them a distanceequal to the thickness of the required slug and of determining thelength of the slug. In other words, termine the dimensions of the slotor mold proper in which the linotype is cast as usual.

When the cap is seated directly on the these liners de-' I liners andthe parts secured by the usual confining devices, the mold will producea slug or linotype of rectangular outline and practically uniformthickness throughout. It is frequently desirable, however, to form thelinotypes, particularly those for very large type-faces and for verylong lines, with cavities or recesses in the side face, as shown in Fig.7, and this for the double purpose of re ducing the amount of metal andthe weight and of reducing the amount of air to be displaced from themold as the metal enters, so that a more solid type-face may beobtained. To this end I provide a core or liner D, such as shown in Fig.6, consisting of a plate of metal adapted to be seated snugly under themold-cap with its ends extended and con fined between the cap and linersO C, so that the underside of the core forms for the time being the topof the mold cell or slot. The under side of the core is formed withdownwardlyextending projections or bosses d to form the cavities orrecesses in the side face of the slug. It will be observed that thesebosses extend to the rear face of the mold, but that they terminate inthe rear of the frontface, so that the front edge of the slug bearingthe type characters is cast of full thickness. It will also be noticedthat the bosses of the core are separated by transverse grooves d, whichform on the slug corresponding ribs -0Z standing out flush with thefront edge of the slug to give the type-face the requisite support andto bear against the adjacent slug in the form.

The ends of the core are preferably notched, as shown at (1 in orderthat they may embrace and be kept in place by the usual end bars or gibswhich connect the cap and body.

The length of the slug produced in the mold is varied by substitutingfor the liner 0 a similar liner of different length, and the thicknessof the-slug is varied by changing both end liners.

When the length of the slug is to be changed, the core D and the liner Cwill be replaced by others of suitable length, or the liner O may'berecessed, as illustrated in Fig. 8, to correspond with the sectionalform of the core, so that the one core may be used with liners ofdifferent lengths, the end of the piore overlapping the recessed surfaceof the nor.

If desired, the liner may be connected to the cap at one or more pointsbetween its ends in order to prevent it from springing away therefrom.This may be accomplished by means of a screw, inserted as shown indotted lines in Figs. 1 and 2, by providing the liner with alongitudinal rib on the upper surface to enter a corresponding groove inthe cap or by any equivalent means.

While the ribs (1 are advantageous in assisting to support the type-faceof the slug and in sustaining the slugs against the compression to whichthey are subjected when the liners are locked together in the form, itis to be understood that they are not necessary in all cases and that inthe case of short slugs, such as those employed in newspapers, a singlecavity in the side, extending nearly the entire len th of the slug, maybe used in the absence 0 any dividing-ribs.

Heretofore molds for casting recessed slugs have been limted to that usealone and were incapable of casting solid or fiat slugs. By means, of myremovable liner, which may be cheaply constructed, I am enabled toquickly convert or adjust an ordinary mold so that it will produce slugsof either form, as demanded.

What I claim as my invention is 1. In combination with alongitudinallydivided slotted linotype-mold a removable core extendingthe entire len th of the moldslot and having its ends con ed by andbetween the mold members.

2. A slotted linotype-mold, having a movable cap, in combination with aninternal detachable core confined in place by the cap and havingprojections to form cavities in the linotype.

'3. As a new article of manufacture, in a linotype-mold, the combinationof the body portion, the cap portion, intermediate liners at the ends,and a removable core, having its extremities confined between the capand the liners, and having its body portion provided with projections toform cavities in the side of the linotype, said projections terminatedat a distance from the front of the liner, whereby the mold is adaptedto form the type-bearing edge of the linotype of full thickness.

4. As a new article of manufacture, a core for linotype-molds having oneor more projections on its side face to form recesses or cavities in theside of the slug, and having its ends extended beyond the operativeportions and fashioned substantially as described for confinement by andbetween the two portions of the mold substantially as described.

5. In a linotype-mold, the combination of cap. and body portions, theintermediate liners, and the core having projections on its undersurface, one of the liners being recessed to admit the projections onthe core, substantially as described.

In testimony whereof I hereunto set my hand, this 16th day of March,1904, in the presence of two attesting witnesses.
